• Description:
  This study identifies and evaluates deposits of noncoal minerals in the United States that are most amenable to be mined underground and transported hydraulically. A method was developed to screen and compare mineral deposits including economic comparisons. The most applicable minerals for hydraulic mining by borehole monitor jets from underground entries are soft uranium sandstones in locations where water is available. This method, with hydrotransport, could improve the safety, health, and economy of underground uranium mines. Soft oil-bearing sandstone could be mined and transported by this method more safely than by other underground mining methods. Many minerals are too hard to be mined by monitor jet but are amenable to hydraulic transport and hoisting. Uranium sandstone is of interest because of potentially improved health and safety in transport and lower transport cost. Increases in mine output for potash and trona can be achieved most economically by adding hydraulic hoisting when existing skip capacity is at its limit. Research is recommended to obtain site-specific data on the feasibility of mining uranium ores by monitor jets. [Description provided by NIOSH]
